UNITED STATES PATENT OFFICE.

IVILLIAM G. LATIMER, OF DETROIT, MICHIGAN, ASSIGNOR TO THE LATIMER CASH REGISTER COMPANY, OF SAME PLACE.

CASH REGISTER AND INDICATOR.

SPECIFICATION forming part of Letters Patent No. 458,811, dated September 1, 1891. Application filed December 1, 1890- Serial No; 373,254. (No model.)

To all whom it may concern:

Be it known that I, YVILLIAM G. LATIMER, a citizen of the United States, residing at Detroit, in the county of IVayne and State of Michigan, have invented certain new and'useful Improvements in Cash Registers and Indicators, of which the following is a specification, reference being had thereinto the accompanying drawings.

This invention relates to new and useful improvements in cash registers and indicators; and my invention consists in the peculiar construction of the mechanism employed in holding up the operated tablet-rods of a cash- I 5 register and in releasing at each operation those that have'been previously operated.

In the drawings I have illustrated my invention as applied to such a cash-register as shown in my patent of August 13, 1889, No.

Figure 1 represents a side elevation of such machine, partly in section. Fig. 2 shows an enlarged detail of the supporting-bar and indicating-rod, showing the parts in their oper- 2 5 ated position. Fig. 8 is an enlarged detail showing a modified form.

A is the casing or frame-work of the machine.

C are the keys, of which there are a series 0 jo'urnaled upon the transverse shaft D.

E are tablet-rods adapted to be moved in suitable guides F at the top. These tabletrods are provided with suitable indicatingtablets G, these parts being of similar construction to those shown in my patents referred to.

In the rear of the tablet-rods is secured a swinging bar II, suspended by the arms I, pivoted to the side of the machine. This bar 40 is provided with a horizontal shoulder .I and with the inclined face K extending from this shoulder downwardly.

Upon the end of each key is formed a cam or inclined bearing L. The lower end of each tablet-rod is slightly widened, as shown at M, or a suitable lug or shoulder N is formed thereon near its lower end. As the forward end of any key is depressed its rear end will be elevated, and it will carry with it the tablet-rod which is supported thereon. These .50 tablet-rods are free to move vertically without interference from the swinging bar H, and as soon as the upper end of the tabletrod has passed the shoulder .T the bar will swing or be moved, so that this shoulder is beneath the tablet-rod to hold it in its elevated position. Now to release this tabletrod so that its tablet G will be withdrawn from view upon the operation of another key, I form the cam L upon the end of the key which at the extreme upper position of the rear end of the key will strike the inclined face K upon the bar and swing it away from the tablet-rods, disengaging any previouslyoperated rod from the bar and allow it to fall to its normal position. The elevated position of the key 2 nd the corresponding position of the bar are shown in Fig. 2..

In case a combination of figures are operated-for instance, suchas 65and the operator desires afterward to operate the 5 alone it is evident that as the key which carries the o-tablet and tablet-rod is depressed its rear end will rise until it strikes the bar and swings it out, as shown in Fig. 2, dropping the previously-operated G-tablet, but holding up the 5-tablct. As soon as the operator releases his hold of the key the keyis free to fall; but the shoulderJ, quickly swinging beneath the tablet-rods, will hold it in its position with its tablet G exposed to view.

From this description it will be evident that the modification shown in Fig. 3 is an equivalent of the construction previously described.

So far as I am aware I am the first to pro- 8 5 duce an indicating supporting-bar provided with a supporting portion, such as J, a releasing portion, such as K, and the co-operating cam or bar, such as L, upon the key, whereby the bar is moved to release the previously-operated tabletrods by the key itself without the intervention of connecting mechanism and without employing any of the other means which have been heretofore devised as accomplishing this result. The bar II may be a swinging bar, as described, or it may be a spring-actuated sliding bar, or any other well-known equivalent may be employed in place thereof. It is also evident that any desired registering mechanism may be cmbearing K, the tablet-rods adapted to en gage with their lower ends upon said shoulder in their elevated position, and a cam L upon the key, adapted to cooperate with the inclined face K to release the previously-operated tablet-rods, the parts being arranged to operate substantially as and for the purpose described.

In testimony whereof I affix inysig'nature in presence of two witnesses.

VILLIAM G. LATIMER.
